Sure they'll tell you that in passing, but won't really explain what that actually means. Certainly Linear Algebra 1 at college was a lot of apply this method to this object (that we'll call a matrix) to calculate this thing called a determinant. Don't worry about what it is or what it represents, just check if it's zero or not. If it's not zero apply this other method to calculate its inverse. Repeat. |
